A kind of insolated stator core combining structure, comprises iron core and end cap, it is characterized in that: described iron core and end cap are one-body molded through voltage stabilizing technique by soft-magnetic composite material respectively, and the two surface has all fitted tightly dielectric film; The height of described iron core is greater than end cap, and the two is equal circular of external diameter, and wherein the upper surface of iron core inner ring is processed with the teeth portion pointing to the center of circle and yoke portion teeth portion connected, and forms a groove between adjacent teeth portion; Being formed with annular groove between the yoke portion of described iron core and outer shroud, being connected, as the accommodation space of motor winding for closing with the bottom of iron core bottom this annular groove.
The material of the dielectric film that described iron core and end cover surface fit tightly is smooth and the sub-film of the good polyurethane of thermal endurance.
Teeth portion, the yoke portion height of the teeth portion of described end cap inner ring, yoke portion and described iron core inner ring front surface superpose and overlap.
The upper surface of described iron core outer shroud is processed with location hole, and the correspondence position of end cap is also processed with corresponding positioning through hole, and the two is connected by fixing pin.
The upper surface of described iron core outer shroud is processed with rectangular recess, when iron core being separated with end cap, can be used as when prizing borrow power mouth.
Technique effect of the present utility model:
1, this patent adopt be soft-magnetic composite material and one-body molded, relative to the iron core that alloy-steel sheet is made, its accuracy of manufacture is higher, processing mode is various, the attaching process of dielectric film is also comparatively simple, and the tightness of laminating is high, and insulation effect is good, and in the running because magnetic circuit is little compared with short magnetic resistance, motor enhancing efficiency is remarkable;
2, this patent have employed the combining structure of " iron core, end cap " formula, and magnetic circuit is able to optimal design, and the rotating speed of the rotor in iron core not only can be made more stable, also protects the winding in annular groove simultaneously, the permeability making it higher and preferably magnetic loop;
3, the high-end coincidence much smaller than iron core and by iron core of end cap covers, and when this iron core combines generation damage, is often that end cap bears damage, and relative to replacing iron core, cost and the replacing difficulty of changing end cap are all less.
